Spark plug with umkapseltem electrode gap, a process for the preparation of an encapsulated spark plug and homogeneous-charge spark-ignited internal combustion engine

摘要

Spark plug (38) with an encapsulated electrode gap, wherein the spark plug (38) comprises:a first electrode (44);an at least a portion of the first electrode (44) which covers the insulator (42);a, with the insulator (42), which is connected to the spark plugs casing (40), wherein the insulator (42) the first electrode (44) with respect to the spark plugs casing (40) is isolated, which has a number of orifices (60) extending has;a second electrode (46), within an ignition chamber (64), which is connected to the spark plugs casing (40); anda separately from the spark plugs casing (40) formed, with an end portion (58) of the spark plug casing (40), which is connected to the spark plugs cap (62).
